i Application filed November 1,1902. Serial No. 129,655, (No model.)

To alt whom, it may concern:

Beit known that I, EDGAR A. NUGENT, a citizen of the United States, and a resident of Unionville, in the county of Orange and State of New York, have invented new and useful Improvements in Bottle-Stoppers, of which the following is a full, clear, and exact description.

This invention relates filled with milk through the operation of a milking machine-such, for instance, as shown in my application for patent filed December 3l, 1901, Serial No. 87,89l-the object being to provide a simple and effectual means` preserving Vthe milk for a greater length ofl time than is possiblewhen the air is contained in the bottles with .the milk.

Il will'describe a bottle-stopper embodying my invention and then point out the novel features in the appended claims.

. Reference is to be had to the accompanying drawings, forming a part of this specification,

in which similar characters of reference indieste corresponding parts in all the figures.

. Figure 1 is a sectional View showing a bottle in connection with an exhaust-pan of a milker and showing the stopper in place. Fig. 2 is a section showing thebottle and stopper removed from the pan, and Fig. Sis atop View of the stopper.

Referring to the drawings, l designates a portion of au exhaust-pan used in connection f with the milking-machine, and this exhaustpan is provide-ri at its bottom wall with a series of openings to receive the necks of bottles. Each opening hasA surrounding it a downwardly-extended and outwardlvared flange 2 for receiving the upper portion of the bottle-neck 3. -To prevent `the entrance of air, a rubberpacking-ring 4 is placed between the iiange and tire bottlelneck. The mouth ofthe bottle has its wall flared, and the entering portion of the stopper 5 is correspondiugly fiar-ed. This stopper may consist of any suitable material-such, forinstance, as hard rubber, or it may be made of glass. On the Y particularly to stop-. pers for milk-bottles that are designed to be` upper portion ofthe stopper are inwardly turned hooks 6, under which the cross-head y 7 of a stopper-inserting rod'8 is designe'dto engage. opening in the top wall of the pan 1. Engag ing around` the neck of the bottle is a yield? ing rubber band A9, whichis designed pri.

This rod 8 is movable through an 55 lmarilyto close'a vent-hole 10 in the neck of l l the bottle. When the bottle is in position or 6o in connectionwith theexhaust-pan, the rubberV band will not only cover the vent, but will engage closely around the outer side of the Hangs 2, thus serving as a means auxiliary to the ring 4. forpreventing any possible 65 entrance of air while'the bottle is being filled.

In the operation the stopper 5 will be raised out of the mouth of the bottle, and thus the milk from the cow will pass into the pan 1 and thence into the bottle. Of course it'will 7o be understood that the bottle is exhausted of air. After refilling the stopper is to be moved downward by means of the rod 8, and then by giving the rod acne-quarter rotation the cross-head 7 may be drawn out through the 75 space between the hooks, after which the bottle may be removed, andin this removing of the bottle the upper portion of the ring 9 will be drawn upward Vand engaged overan annular bead 11 on the stopper, as indicated 8o in Fig. 2. This of course closes the vent 10. Whenit is desi-red. to open the bottle, it is obvious'that air must be admitted before the stopper can be drawnout. To admit the air,- it is only necessary to raise a portion of the 85 lower part of the ring 9 above the vent 10.

The itmslportion of the stopper is made cupshaped, so that should the bottle or can be full of milk the stopper may beinserted. L`

While I have described the stopper in con-L 9o nection with a milk bottle or can, it is obvious that it may be used for fruit-jars or the like. I

Having thus described my invention, I claim as new and desire to secure by Letters 95 Patent- 1.

V1. A bottle having a vent in its neck portion, a. stopper for the bottle, hook members on the top of the stopper and a flexible ring' for engaging with the neck of the bottle and roo with the stopper, and for covering said vent, substantially as specified.

2'. A bottle and a'stopper for the bottle havin`ginward1yturned hook members on its up- 'per side, substantially as specified. 3 3. 'The combination with bottle having a. f5 vent in vthe upper portion of its neck, yof a @stopper having an annular bead, inwardlyturned hook members on the upper side 'ofthe etopper, a, rnbber-1ing er band for engagingraronnd the peek of the bottle to eove'the vent and also.adapted to engge with said log;

bead, substantially as specified.

In testimony whereof I have Signed my name to this specification in the presence of -two subscribing witnesses.
